APPARATUS FOR REPAIRING INDIA-RUBBER GOODS.

' To all whom it may concern:

cially though not exclusively,

' of this invention.

*SPRIGGS, a sub ect ofthe Kin of England, and a resident of Leicester,invented certain new and useful Improvements in or Relating to Apparatusfor Bepairing India-Rubber Goods, of which the following is aspecification.-

This invention relates to an ap aratus for repairing india" rubbergoods, eing speapplicable for mending or stopping holes or fractureswhich'may have occurred in rubber gloves.

The invention consists of a portableelectrically heated vulcanizingapparatus, comprising a heater or metal bar mounted upon a wooden orother non-metallic base plate and arranged to be coupled up to a wire orwires leading from any suitable source of electrical current or energy.Cooperating with the said heater are one or more bars .or trees upon orover which the fractured finger or thumb of a glove may be drawn priorto being repaired. The said treesare hinged or pivoted at one end topermit of being moved up or down for the purpose of placing thereon orremoving therefrom the glove before and after repair, and also to allowthe tree to bemoved relatively to the heater. .The trees may beindividually movable relatively to the heater or a plurality of them maybemovable in company.

Means are provided to lock the trees in position with their ends on theheater. These means may lock the trees individually or it may bearranged that a number of the trees may be fastened by a common lockingmeans. a

Provision may be made'for the removal of the trees so that trees ofdifferent sizes or' shapes may be used when required.

In further describing the invention and the manner of using theapparatus reference will be made to the accompanying drawing; wherein IFigure 1 is a perspective view of an ap-' 'paratus which constitutes oneembodiment Fig. 2 is a plan of the same. Fig. 3 is a plan showing amodification of the means employed for fastening or ngland, have.

locking the trees. Fig. 4 is a plan of a modified arrangement of thetrees.

Like parts are designated by the same reference characters in all thefigures of the drawin A. vulcanizing apparatus according to thisinvention comprises a heater 1 consisting of a metal bar or bed adaptedto be heated electrically in any known manner said heater being mountedupon a wooden or other nonmetallic base plate 2. The base 2 may beprovided with a suitable coupling or plug 3 to which connection may bemade from any convenient source of electrical current to supply theheater 1.

The article to be repaired is pressed upon the heater 1 by a tree andalthough the invention is intended to cover apparatus havonly one tree,nevertheless it is preferab e that a plurality of trees be provided. Thesaid trees 4 are movably carried on the base plate 2 and consist offingerlike bars composed of Wood. or some other material which is a goodnon-conductor of heat. It may, however, form the trees partly of metalthe tips or ends which make contact with the heater being made of woodor other non-conducting material. The trees a are hinged or pivoted sothat they may be turned or moved to and from the heater as shown in Fig.1, thus permitting the goods to be readily placed on and remove from thetrees.

The locali y wherein fractures most commonly occur in rubber gloves isat'the ends of the fingers, hence the end of each tree 4 ,may be formedwith a flattened extension or continuation 5. When the fracturedfinglove is drawn upon the tree, the fracture or hole is located on theflattened portion 5 and then when the tree is brought down into.position on the heater 1 the fractured part of the glove is pressed intoclose contact with the surface of the heater, as

hereinafter described. 1

. Conveniently the trees 4 may be movably mounted at one end upon a rod6 or equivalent, said rod being carried by brackets or plates 7 attachedto the base plate 2. The rod 6 may be withdrawable from the be foundadvantageous to.

. heaterl, t

passing throu brackets to 'peit the-removal, renewal or exchange of thetrees. 4 The rodmay'be kept ovals company and yet be'capable ot. 1.separated and turned individually 'if-ueeds be. .To this end, an elasticband, 9 era spring' or equivalent may be located "around or passed throuh those treesit is 'a aml to couple toget er in the manner mentioned: InFigs; 1 and 2,.sets ofthree and ,four trees areconnected by bands 9which latter yieldingly connect the trees in eachi-eet-sothat they maybe operatediin the mannerust mentione j gIn Fi .4 isshown-a modificationwherein a plurality of trees are integrally connected in which case thgyare all movable tegether (1 no individu movement ofthe trees'isprovided. b 1 Instead of the foregoingyarrangements, a lete hand tree(not shown) may be emp oyed withthe fingers and thumb separately hingedorv movable up and down relatively to the-heater 1 for-the purposehereinbeforementioned' For Iocki'ng'the trees 4 p tr 1: a. theretowhenthey are in the operative position, a; e. turned down upon the suchas shown in- Figs-J.- .{and 2 may be provided said means consist of abar'loadapted to extend across the *trees'and-M ti htened by wing nuts11 on bolts or screwe rods The screwed rods 12 are suitably attached'tothe base plate 2 and, the bar may be turnable on one of the rods. as apivot sothat it can be brought. into and out of position over the treesas shown in Fig. 1., Suitable springs .24 se cured to the underside ofthe barlO serve to 'maintain the desired pressure upon the In thearrangement of locking means just "described the bar 10 operates.simultaneously upon .a plurality of trees but in a-modified arrangementthe trees may each be locked in the working position by independentmeans consisting, as shown'in Fig. 3, of a wing nut 13 one stud orscrewed rod 14.- the latter ha slot lfi-inthe tree. The studs 14k are edin the base plate 2 and when the-trees 4 are brought down: bathe wonkipesitioatbe-ends of the studs pro--. st at the slots 15 and their the atmaybe appliedandtighed-dowmr-up' as. p l in amassearrangement of treesshown in Fig. at but preferably the bar form is used.

dhthermometer 1 6. (Fig. 2) is combined with the heater 1 "so as toindicate the'de'gree to whicli 'the Heater-is heated. "In practice theglove finger is drawn over the tread sc -that the fractured. art'is asbefore stated at'the extreme and atten'ed end 5'} thereof upon which.itis-stretched or flattened out. A'small wad or piece of rawrubher isthen placed -0n'-or ever the fracture with or without the previousapplication thereto of a suitable substance to act .as a flux and thetree'is loweredon 'to' the heater l-and locked thereon, the lockingmeans being tightened so as to cause the tree to press on the heater, inwhich pom'tion it remains until the heatefiects the fusion and union ofthe wad and-the glove and the repairofthe fractureis-coinplete. -'lhebase plate 2 has a drawer 17jfor con H. spare trees and other'items foruse in connection" with theapparatus.

In the form of apparatus'illu trated in- Figs. '1 and 2 two separatesets of trees are arranged to cotiperate withthesame heater "each setot'trees havinga separate locking device. I I r It is to be understoodthat the invention is not to be limited to any particular munber oftrees-or sets of trees which may be arranged to cooperate with the sameheater. en the I means consist of a bar such as 10 it willbe obviousthat any or all of the treesin-the set with which said bar is employedmay be used at one time, those which are not required may be left turnedback a. e. in the non-working position.
